motors and particularly to intake headers therefor.

One object of the invention is to provide a simplified cooling system for the motor enabling the water to pass directly from the cylinder heads to an intake header jacket or chamber and then directly to an outlet leading to a radiator or other cooling device.

Another object of the invention is to provide means to impart the maximum heat from the water in the circulation system to the vapor intake chamber forming a part of said header.

Another object of the invention is to provide a header having a water heated vapor intake chamber which shall obtain the above objects and which offers only slight head resistance.

Another object of the invention is to pro vide such an arrangement of the intake header and its connections as to afford a rigid cross tie between the cylinders of the two rows in a V-type engine such as this invention is particularly designed to be applied to.

Another object of the invention is to utilize the carbureters as part of the means for providing the rigid connection between the cylinders.

Another object of the invention is to provide an effectively sealing means of simple construction at the joints between the car bureters and the walls of the vapor intake chamber of the header.

lVith these objects and others in view, the invention is embodied in preferable form in the construction and arrangement hereinafter described and illustrated in the accompanying drawings, in which- Figure 1 is a top plan view of part of a hydrocarbon motor showing one end of the intake header;

Fig. 4 is a side View in elevation partly in section, showing a part of the header and the carbureters which are connected thereto; and

Fig. 5 is a vertical section on the line 5-5 of Fig. 3.

Referring to the drawings, 1 indicates the.

cylinders of a hydrocarbon motor, which cylinders are shown as arranged in two rows with the axes of the cylinders in the respective rows arranged at a V-angle to one another. Preferably these cylinders as shown are arranged in groups of' two, although other groupings of the cylinders may beemployed if desired. A water jacket 2- surrounds each group of cylinders.

Mounted in the space between the cylinders but above the level of the upper ends of the latter is the intake header, constitut ing an essential element of the invention. This header comprises a plurality of hollow bodies 3 the lengths of which extend parallel to the length of the motor and of which one body is adapted to correspond to andtake care of-the supply of gas to a number of cylinders in one row and the water chamber of which is adapted to take care of a plurality of water jackets in the same row, while. the other body is adapted to co-act with cylinders and jackets in the other row.

In the embodiment of the invention herein illustrated two of such hollow bodies are shown and they consist of substantially rectangular members extending from end to end of the rows of cylinders and arranged substantially parallel to one another. The

upper outer surface of this header lies in a horizontal plane, thereby reducing head resistance. Each header member is provided with a horizontal partition 4 extending from end to end of the hollow member and located nearer to the top wall of the header than to the bottom wall and providing a vapor intake chamber 5 and a smaller water circulation chamber 6 superposed on the vapor intake chamber. The waterwhich circulates through the chamber 6 is delivered thereto from the jackets surrounding the engine cylinders and is adapted to impart its heat to the explosive mixture enteringthe vapor intake chambers 5 in order to increase the combustibility of the mlxture. The lower chamber of the header forming the vapor intake chamber is divided into two compartments by means of a central vertical partition 7, one of these I compartments corresponding to one-half of the cylinders on one side of the motor and the other compartment corresponding to the remaining cylinders on the same side of the engine. Two carbureters are shown as adapted to supply the explosive mixture to. the intake chambers. Each carbureter is disposed between the central transverse line of the motor and one end thereof. Each carbureter 8 has an integral casting 9 forming the base and two separated upwardly extending branches 10 of which one is adapted to join one of the compartments of an intake chamber 5 of one of the header members 3 and the other is adapted to join .another compartment of the chamber 5 in the other hollow header member 3.

surrounding each opening and against the lower edge of which the upper edge of the carbureter branch pipe is adapted to abut. The adjacent parts of the annular vertlcal walls of the pipe 10 and depending flange 11 are recessed to receive an annular sleeve or ring 12 which provides a double broken joint between the pipe 10 and the header and thereby serves effectively and by a simple construction to seal the junction between these parts and prevent the escape of the Each carbureter branch pipe 1-0 is provided atits upper edge with lateral flanges 12 through which extend bolts 13, the heads of which are adapted to engage lugs 14, one of which is formed on each of the hollow header bodies 3, and which lugs are adapted to abut against one another along the central line between said bodies. 'These bolts serve to suspend the carbureters and hold the upper'ends of the carburetor tightly against the header flanges.

The upper water receiving chamber 6 of each header member is provided with an opening through a lateral boss 15 adapted to communicate with a downwardly extending conduit pipe 16. One of these pipes is shownleading from the hollow header member chamber to each. of the water jackets surrounding two of the cylinders as indicated in Fig. 1. The water which has absorbed the heat from the engine cylinders is thus conducted upwardly therefrom in the natural direction of flow directly to the water receiving chamber 6, thus providing a short direct path in the line-of circulation from the hottest part of the system toward the coolest part. These pipes are connected to the jackets by means of a flexible coupling'16' of rubber or other yielding material whereby allowance is provided for yariations in the relative locations and sizes of the parts to be connected.

In its upper wall the chamber 6 of each hollow body of the header-has an opening 17 leading into a common casing 18 with which communicates a single outlet pipe 19 which preferably is adapted to lead to a radiator not herein shown. The casing 18 is provided with a flange 20 entirely surrounding the same and having a flat under surface which is adapted to fit upon the flat exterior faces of the two members of the header and which is rigidly bolted'to said members and thus constitutes an upper cross connecting member for the two header bodies. The two header members are thus rigidly connected by the cross connection at the bottom afforded by the carbureters, the cross connection at the top provided by the flange 20 and the vertical connection obtained by the bolts 13.

Leading from the vapor intake chamber 5 to the respective cylinders on one side of the engine are separate gas conveying pipes 21, which rigidly tie the cylinders to the headers, thus preventing vibration of the cylinders at their upper ends.

With the arrangement above'described, as the explosive mixture'is admitted'to the intake chambers of the two members of the header from the carbureters it will be heated by the water carried into the upper chambers 6 from the pipes 16 which communicate with the water jackets. It will be seen that these water jackets are separately connected in parallel to the header members at separated points along the length of the header and by short pipes at right angles thereto, thus afl'ording a direct path for the heated water in the direction of the normal flow of the water from the hottest to the coolest part of the system, and preventing heat loss by radiation through long conduit pipes, thus obtaining the maximum heating effect upon the gases in the lower chambers in the header. This heat utilization is further insured by reason of the longitudinal extension of the headers lengthwise of the motor, thus providing an extensive radiating surface for the heated water; By thus extending the headers and forming them with a flat external horizontal surface-this extensive radiating area is obtained without producing any obstructing body such as would tend to increase the head resistance. Since the header members are rigidly tied together at the top and bottom and are rigidly connected at separated points by the gas conduit pipes to \the cylinders 'a rigid cross tie for the upper ends of the cylinders surface lying in substantially a horizontal plane, and having a partition lying in substantially a horizontal plane and dividing the body of the header into a lower vapor intake chamber and an upper water chamber.
